Hello Support Team!
Please let me know how can I change the scale transform of radListView ?
It is possible with hierarchy but how does this happen via code?
Thanks.

I have a Windows Forms application (C# .NET 3.5) which uses RadChart and RadMenu controls (version 2009.1.9.311).  I can build and run the application on the build machine (Windows 7 64-bit), but it crashes immediately when run it on any other Windows 7 64-bit PC.  I created a new test application with nothing except one RadChart and it also crashes immediately.  As soon as I click on the executable it displays the standard Windows "[program] has stopped working" error with the choice to check online for a solution or close the program.  The original application has the following details "Problem Event Name: APPCRASH; Fault Module Name: KERNELBASE.dll; Fault Module Version: 6.1.7600.16385; Exception Code: e0434f4d; Exception Offset: 000000000000aa7d; OS Version: 6.1.7600.2.0.0.256.4".  The test application only as a few details which might be useful: "Problem Event Name: CLR20r3; Problem Signature 03: 4call1179b; (PS 06 is the same); Problem Signature 07: 1; Problem Signature 08: 15; Problem Signature 09: System.IO.FileNotFoundException; OS Version: 6.1.7600.2.0.0.256.4".  I can create a similar test application with non-Telerik controls and do not get the error on other Win 7 x64 PCs.

Has anyone else experience similar issues?  Is there a solution / workaround?

Thanks,
Chris

Hello,

i need a solution, that the user only can make time inputs in 15 minute steps. For example:

08:00
08:15
08:30
....

Is there a opportuniy, special for the arrow keys, when he clicks on it and the minutes are chosen, that the tick is 15 minutes and not 1 minute?

Greets,

Hi, 

I'm currently trying to reproduce the grid that is shwon in the ecran.jpg attachment.

I'm using the hierarchy grid view, but it doesn't seem to work when I try to do a hierarchy with more than 2 levels, the grid won't show the third level in my web app.

Do you have any insights on how to do a grid with more than 2 levels ?

Thanks in advance

I wish to add a key or a tag with each node (db record id) so when the user selects the node, I can retrieve the key or tag and go query the database.

Suggestions on how to store the key during node creation(node.add) and retrieval would be helpful

Hi,

I am using a Telerik's GridView and experiencing the following issue:
Each row in the gridview has a checkbox, so does the header of the Gridview (to select or deselect all the rows).

There is sorting that works fine everytime I click on column headers.
But when I click on the checkbox in header to select or deselect all rows in the grid, the column headers disappear.

When I switch off the sorting functionality - checkbox works fine and headers are not missing.

When I switch on the sorting functionality, the sorting works fine when clicking on column headers, but again when clicking on header checkbox to select or deselct all rows - headers disappear.

I would appreciate any advice.

Thank you,
Tanya

Hi,

I am using RadControls for WinForms Q1 2011 and Visual Studio 2012, Ultimate Edition to develop a .NET4.0 app.
The app uses RadTreeView for showing a very simple file system explorer and removes nodes in two cases:
1. On NodeExpandedChanged the event handler removes a dummy node representing a collapsed directory with a new node.
private void OnDirExpandedChanged(object sender, RadTreeViewEventArgs e)
{
    if (e.Node.Expanded)
    {
        if (e.Node.FirstNode.Name == "____dummy____")
        {
            m_fileExplorer.BeginUpdate();
 
            RadTreeNode l_parent = e.Node.Parent;
            int l_nIx = e.Node.Index;
 
            e.Node.Remove();
 
            RadTreeNode l_new = CreateDirNode(new DirectoryInfo(e.Node.Name), true);
            l_parent.Nodes.Insert(l_nIx, l_new);
            l_new.Expand();
 
            m_fileExplorer.EndUpdate();
        }
    }
} // OnDirExpandedChanged
This code works just fine.

2. On EventArrived fired by System.Management.ManagementEventWatcher upon CD insertion/ejection the event handler removes either a node representing the empty drive or a node representing the CD file system.
Currently I narrowed the code just to the attempt to remove a CD node
private void OnCdInsert(object sender, EventArrivedEventArgs e)
{
    ManagementBaseObject l_wmiDevice = (ManagementBaseObject) e.NewEvent["TargetInstance"];
    string l_sDriveRootDir = l_wmiDevice["Name"].ToString() + Path.DirectorySeparatorChar;
 
    int l_nIx = m_fileExplorer.Nodes[0].Nodes.IndexOf(l_sDriveRootDir);
 
    m_fileExplorer.Nodes[0].Nodes[l_nIx].Remove(); // (1)
    m_fileExplorer.Nodes[0].Nodes.Remove(l_sDriveRootDir); // (2)
} // OnCdInsert
I tried different ways of removing the node, I tried wrapping the code with BeginUpdate()/EndUpdate(), I tried calling Invalidate() or Refresh() - the result is always the same
a) The node itself is still shown, although the debugger shows that the nodes count has decreased;
b) Expanding other nodes, e.g. a node representing C:\, does not work any more, i.e. the event is fired, but view remains unchanged.

Note: The only difference between the nodes removed in the cases #1 and #2 is that OnDirExpanded() removes only grandchildren or farther of the root node, while OnCdInsert() removes a child of the root node.

I am really lost and your help is my only hope now.

I am looking forward to your assistance and thank you in advance for it.
